By default, the WSHumanTaskHandler also completes the human task node if the human task has been failed (check out the source code for details: http://anonsvn.jboss.org/repos/labs/labs/jbossrules/trunk/drools-process/... ). You can easily change this behaviour by implementing your own handler though. You could for example add the task as a result parameter, or add a status result parameter that contains the final state of the task. Simply add these to the results map in WSHumanTaskHandler.GetCompletedTaskResponseHandler.
